' Application filed DeoemberlB, 1897. S rial ITO-662,453. on model.)

To all whom it JewybhncernQ- t Be it known that -I, ErIRIOO BOTTINI, a citi- Zen of the United States, residing inthe city and county of San Francisco, State f..Cali-;v

fornia, have invented certain new and useful. Improvements in Air Compressing'Apparatus for Vessels, of which the following is a spec}- I movements of the vessel in the water for the "fieation.

apparatus for compressingair by the combined force 'of the waves and the movements of a ship'or vessel to which the. same is ap-.

plied; andithe invention consists in certain inovel construction'of parts and combination of parts and their arrangement'on a' ship 'or .Yessel; as hereinafter described, and pointed out in the claims at the end of this specification. The same have for their object to produce and supply'a body of eompressed'airi by thecombined force of the waves and the purpose of ventilation or to operatean-auxiliary engineto do usefuLwork on .the vessel or to augment the'motive powerto propel-th vessel. 1 v v The following description explains atle ngth the nature of my said invention and the man- 'ner inwhich I proceed toconstruet,apply,

and carry out the same, reference being had to the'drawings that accompany and i'orr'n a' part. o'f-this 'speeification.'

In the said drawings, Figure 1 is an ideal representation of the hull of a vessel with 7 vertical transverse section. 'Figr tis-a de- 4o tail sectional view. on anenlarged scale, of'a' 1 to'which the pump-rods are connected.

my apparatus applied to and arranged on the same for operatigm.v Fig. '2 is a planer-top view of the same at the bow, and'Fig. 2 a

a plan of a-portion of the hull'a't the stern." Fig. 3 is an jend elevation with one-half inpair of compression-pumps, their i-nclosing chamber, and-the float beneath the chamber Av indicates the hull of a vessel on which this apparatus is arranged for operation.

bers arranged along the'sides of the vessel above the load-line and'either securely fixed on the outside of the hull or constructed in- .tegrallywith the hull at the time of buildin O O are compressing-pumps fixed in each,

cha1nber,and D D are the piston-rods'of the pumps.

E is-a floatlocated beneathjthe bottom of the chamber B, arranged so as to play perpendicularly or move up and down under the contact orimpaet of the Wavesagainst the bottom or under side of the float and having l 4 1 p the piston-:rodsD D secured to it. My-inven'tion relates to. improvements in D' is an inlet in the top of the compart- 'ment Bthrough which .air is drawn in by the pumps, andFis a suetioufor inlet valve in each pump-cylinder.

G-is at'ube leading fromthe pressure side of the pump into anair-tight tank or storag compartment H inside thelv'essel, I

Cheek valves g are placed", on the outlet ends of the tubes G'to prevent backward pressure of the air.

,The tank-H is carried around the inside-of thegunw'ales or sides of the upper'd'eck, so 1 as to take the discharge-tubes G of all the .pumps, andit is either carried around the ends of-the vessel at thestem or the ste'rn,'or the tank on one side is connectedwith that on the other side of the hull by-one .or-more from these pipes other eonductorsare laid to difierent points for carrying the air-from the storage-compartments to parts of the vessel where it is required for use.i Bya singleconduetor these pipes can be connected with a The floats E, through the medium of which the lifting force or power of the water .is applied to work the pumps, are guided and pipes 78, as indicatedin Figs. 2 and2; and

compressed-air engine in cases where sufficient'foroe or pressure is generated and stored in thetanks to Work an engine. of that descriptioneither to perform work, auxiliary to the main engine orv to aid in the propulsion of the vessel where the same is, propelled by maintained in working position by the pistonrods in the perpendicular movements; but additional guides are employed when required for the purpose of insuring. a perpendicular lifting in the same plane under any irregi lar or variable pressure of the water against one end over the other end of the float.

Theseadditional guides are composed of rods Z, fixed to the'fioat near the ends and working upward through guiding-apertures the Ice bottom of the compartment 13, as indicated in Fig. 1.

The floats E are weighted, so as to descend as the force of the waves orwater acting on them is withdrawn from against their bottom surface.

As thus constructed and arranged for operation,the rising and descendingmovemcnts of the fioats at the sides of the vessel under the impact of the waves against them from beneath and the rolling motion of the vessel is caused to work the pumps in the two sets of compartments B, and the air drawn in through the openings in the top of these compartments is forced by the pumps into the compartments II, which I have termed the storage-tanks.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination in and with a vessel, of air-receiving compartments arranged exteriorly on the hull and communicating with the atmosphere; air-pumps in said compartments provided with inlet-ports and pressure or discharge ports and having piston-rods extending through the bottoms of the compartments; floats beneath saidcompartments hav- I ing rising-and-falling movements under the impact of the waves from beneath, said floats being connected to the piston-rods; storagetanks within the vessel and air-conductors connecting the discharge-ports of the pumps with said tanks, and check-valves in said conconductor connecting the discharge-port of the pump with the storage-tank and having a check-valve; and a float beneath the pumpcontaining compartments connected to the piston-rods 0E thei'pnmp, and adapted to rise and fall .nnderthe impact of the waves acting against said float from beneath, substantially as described.

I11 testimonythat I claim the foregoing I have hereunto set my hand and seal.
